Understanding South Dakota Income Taxes
South Dakota levies no state income tax on wages, so your 2025 tax picture is federal income tax plus FICA payroll taxes. South Dakota runs on its 4.2% state sales tax plus municipal sales taxes, tourism, and revenue from its large financial-services and trust industry — with no personal or corporate income tax.
Key Takeaways for 2025
- Federal tax brackets and standard deductions have been adjusted for inflation (and raised retroactively by the One Big Beautiful Bill Act).
- South Dakota has no state income tax — retirement income and Social Security are untaxed at the state level too.
- Don't forget FICA taxes (Social Security and Medicare) — they're withheld from your paycheck automatically and included in the take-home figure above.
